i may not know the answer scientifically but i do know the ice does get colder. i remember doing this process to create home-made ice cream xD
Adding salt to ice decreases its melting point. Adding salt to the top of ice helps melt the ice faster.
Ice cream melts when you boil it.
Ice will be cool at 10 degrees Celsius
nothing, it's only effective when salt is sprinkled ON the ice.
I assume you are asking why salt melts ice. It's very difficult to tell from your question... What happens, is that ice always has a thin layer of liquid water on it. When salt disolves in water it produces heat, melting the ice, providing more liquid water to disolve the salt into.
When salt is added to ice, the melting point goes up, causing the ice to melt faster. That's why is cities where ice frequently is one sidewalks in winter, people shovel salt onto the sidewalk.
About 80% of the salt is initially not incorporated, and that 80% just drains back into the ocean.
It gives you a freezer burn
Yes, in fact it doesnt melt. The salt goes through the ice, then make little holes in the ice.
They stay right in the salt shaker where they are suppose to be.
It melts slowly.
Salt decreases the freezing point of water, causing the ice to melt. This happens because the salt lowers the temperature at which the ice can exist in a solid state, leading to the ice absorbing heat from its surroundings and melting.
